If you're curious about making the switch to shampoo bars — or still on the fence — you're not alone. Shampoo bars are one of the most talked-about sustainable swaps, and at The Earthling Co., they're the product that started it all. With 63,548+ five-star reviews, our products have become a community favorite — proving that you don't need plastic bottles to achieve healthy, happy hair.
In this guide, we're breaking down everything you need to know about shampoo bars — from how they work to customer-loved benefits, common myths, and tips for getting the best results.
What Is a Shampoo Bar?
A shampoo bar is a solid, concentrated version of liquid shampoo — without the plastic packaging or unnecessary fillers. Our bars are made with plant-based ingredients and are free from harsh sulfates, silicones, and synthetic fragrances, making them gentle on both your hair and the planet.
Why Make the Switch?
According to our community, these are the top reasons Earthlings love our shampoo bars:
- Plastic-Free Packaging: One shampoo bar can replace up to three plastic bottles.
- Travel-Friendly: No spills, no TSA restrictions — perfect for on-the-go.
- Long-Lasting Formula: Each bar lasts between 50-75 washes, outlasting most liquid shampoos.
- Cleaner Ingredients: Free from sulfates, parabens, and synthetic fragrances.
- Great for All Hair Types: With five scent options and a fragrance-free version, there's a bar for every hair type and preference.

Shampoo Bar Myths vs. Facts
Let's bust some common misconceptions:
| Myth | Fact |
| Shampoo bars don't lather | Our bars create a rich, luxurious lather without sulfates. |
| They're drying for hair | Our bars are formulated with hydrating ingredients like coconut oil and cocoa butter. |
| They don't work for thick or curly hair | Thousands of curly-haired customers swear by our bars for defined, moisturized curls. |
How to Use a Shampoo Bar (Step-by-Step)
- Wet your hair thoroughly.
- Rub the bar between your hands to create a lather, or glide the bar directly onto your scalp.
- Massage into your scalp and hair, just like liquid shampoo.
- Rinse thoroughly.
- Store your bar in a dry spot (like a soap saver bag or draining dish) to make it last longer.
